During operation:
•
Each time openers are lowered, hold tractor remote
hydraulic lever forward for a few seconds to recharge
circuit, then return it to its neutral position. The
tractor and drill should be on level ground when
returning tractor lever to neutral.
•
When approaching rough terrain where you need
active hydraulics to maintain even opener
penetration, push tractor hydraulic lever forward
momentarily. As soon as you return to level ground,
return lever to neutral. Do not activate tractor
hydraulic lever for more than 20 seconds at a time,
once every 2 minutes. Always wait until tractor and
drill are on level ground before returning lever to
neutral. You can bump tractor hydraulic lever forward
any time on level ground to assure the preset
pressure is correctly locked in and to reset the
system.
•
Always raise openers before turning. Never back up
or turn sharply with openers in the ground. Doing so
will plug openers and may damage equipment.
